The 510 Atty RDA is a rebuildable tank atomizer by 510 Distro that lacks in size but packs a serious punch in flavor quality and vapor production. The 510 Atty is constructed from a durable 304 stainless steel, comes equipped with a delrin base to aid in heat dissipation, and has a velocity style two post design that allows for quick and easy wicking and custom coil building. This RDA also features a 22mm width, a silver plated contact pin and comes with extra o-rings and phillips style screws to keep your new 510 Atty RDA working like new for quite some time to come.
